Question

当春天加载EntityManagerFactory时，我正在使用最新的springframework disto v4.2.5.RELEASE和Hibernate v5.0.7.Final我得到以下异常

Caused by: org.hibernate.HibernateException: Not all named super-types (extends) were found : [com.sample.model.Sample]

相同的代码正在使用v4.2.5.RELEASE和Hibernate v.4.3.10。

我知道Hibernate改变了v5.x中的核心元数据构建，是否需要在JPA / EntityManagerFactory / Hibernate属性的spring配置中指定它以使其与Hibernate 5.x一起使用？

@Entity
@Table(name = "tbl_sample")
public class Sample extends Auditable {
  private Long id;
  @ManyToOne
  @JoinColumn(name = "relationA", nullable = true)
  private RelationA relationA;
  ... etc
}

@MappedSuperClass
public abstract class Auditable extends Persistable {
   //audit props
}

@MappedSuperClass
public abstract class Persistable {
   //common props
}

我可以在启用跟踪日志后缩小问题范围，还有一个类正在扩展Sample Class，并使用hbm.xml映射，如下所示

<hibernate-mapping package="com.sample.model">  
  <joined-subclass name="BloodSample" table="tbl_blood_sample"
   extends="com.sample.model.Sample">
   <key column="ID" />

  <property name="sampleNo" column="sampleNo"/>
   etc....
 </joined-subclass>

我删除这个关系的那一刻hbm它开始工作了......仍然想知道为什么它现在正在发生，而不是旧版本的hibernate。

所以我想这个问题与spring无关，但与hibernate有关。任何见解？

我有类似的问题。您尝试在hbm.xml文件

中对class标记而不是joined-subclass标记

升级到Hibernate 5.x后，Spring无法创建EntityManagerFactory
